We’ve come a long way in our ability to restore missing teeth. Today’s top choice is dental implants, prized not only for their close resemblance to real teeth but also their durability.

The rise of implants, though, hasn’t put older restorative methods out to pasture—many continue to offer patients a viable and affordable choice for tooth replacement. One example is the removable partial denture (RPD).

Once quite common, RPDs’ popularity has only slightly diminished with the advent of implants. They’re a fair option in terms of dental function and appearance, and much less expensive than implants or fixed bridges.

Similar to a full denture—a removable appliance that replaces all the teeth on a dental arch—a RPD can replace multiple missing teeth in a variety of configurations. A traditional RPD is usually constructed of vitallium, a lightweight but strong metal alloy, which allows for a very thin and comfortable frame. It’s covered in a gum-colored resin or plastic with prosthetic (false) teeth precisely set at the missing teeth’s locations. The appliance stays in place through a series of clasps that attach to the remaining teeth.

Each RPD is custom-made to fit a patient’s mouth contours and the locations and patterns of the missing teeth. The top design goal for each individual RPD is to minimize any rocking movement during chewing; achieving that goal will depend not only on how many teeth are missing and where, but also what type of teeth are being replaced. For example, teeth missing from the back would require a different support design than teeth missing from the side or front.

RPDs’ biggest benefits are comfortable fit, effective dental function and good appearance. However, their means of attachment can create difficulties keeping remaining teeth clean of disease-causing bacterial plaque. Furthermore, an ill-fitting or unstable RPD could damage or even loosen natural teeth. It’s therefore essential for wearers to diligently practice daily hygiene (including cleaning the RPD) and undergo regular fit monitoring with their dentist.

Even with these constraints, a RPD can do an acceptable job providing dental function. What’s more, it can definitely improve your smile.
